Area forecast discussion, Jul 7, 1:36 PM EDT, 57 minutes before

Area Forecast Discussion
National Weather Service Northern Indiana
136 PM EDT Wed Jul 7 2021

.SYNOPSIS...
Issued at 1247 AM EDT Wed Jul 7 2021

Warm and humid conditions will persist today with chances for
scattered showers and thunderstorms increasing this afternoon into
tonight. Clouds and chances for rain will linger into Thursday,
especially across northeast Indiana and northwest Indiana, with
dry and cooler weather anticipated by Friday.

&&

.SHORT TERM...(Today through Thursday)
Issued at 300 AM EDT Wed Jul 7 2021

Latest surface analysis has quasi-stationary frontal boundary
extending across the central great lakes and back into the mid-MS
valley. Water vapor imagery depicting short wave energy moving
across Iowa and this feature expected to combine with frontal wave
to drag frontal boundary closer to the forecast area bringing
increasing chances for showers/storms to develop this afternoon.
HREF members indicating pre-frontal trough expected to initiate
convection over the area early afternoon as airmass destabilizes
during peak heating with surface based CAPE of 1500-2000J/kg along
with ample low level moisture. Forecast soundings indicating weak
flow through the column which will be main limiting factor for
severe storms although 20-30kt effective shear in northern CWA will
be supportive for locally strong storms. Shower and thunderstorm
chances continue into Thursday as main upper trough axis moves
across the great lakes region pushing surface frontal boundary east
of the area late Thursday. Could again see some stronger
storms in eastern CWA Thursday afternoon prior to frontal passage as
CAPE approaches 1500J/kg. Warm and humid conditions continue today
with dewpoints still hovering around 70F and highs 85-90F. Frontal
passage will bring cooler and less humid conditions Thursday
especially western CWA with highs 75-80F.

&&

.LONG TERM...(Thursday night through Tuesday)
Issued at 300 AM EDT Wed Jul 7 2021

Brief break in an otherwise active pattern to begin the long term
period as weak surface high settles into the area Thursday night and
Friday. Focus then shifts to short wave energy coming onshore in the
Pacific Northwest that will top the western US ridge before closing
off over the mid-MS valley this weekend. Stalled surface frontal
boundary over the Ohio River valley will lift back north as a warm
front ahead of this system and bring a prolonged period of precip
chances to the region. Surface low development to the west of our
area will bring potential tapping of gulf moisture into frontal
boundary and heavy rain development. Uncertainty lies in location of
heavy rain axis given range of timing/placement solutions offered by
models with NBM shifting focus further south/west of our area over
the past 24hrs. Will therefore opt to keep POPs in chance/high
chance range until better model consensus is realized.

&&

.AVIATION...(For the 18Z TAFS through 18Z Thursday Afternoon)
Issued at 136 PM EDT Wed Jul 7 2021

Scattered convection is developing this afternoon and will
continue into the evening as weak ascent overspreads an
increasingly moist and unstable airmass. Brief gusty winds and
IFR/MVFR restrictions will be possible with any convection. A cold
front then works through or near KSBN by later tonight with low
stratus potentially building in. Some fog may also be possible at
both sites, but FWA ceilings should stay MVFR.
